 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mGoogleSignInClient = GoogleSignIn.getClient(this, new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_GAMES_SIGN_IN).build());
}

@Override
   protected void onResume() {
       super.onResume();
       signInSilently();
}

private void signInSilently() {

    mGoogleSignInClient.silentSignIn().addOnCompleteListener(this, new OnCompleteListener<GoogleSignInAccount>() {
    @Override
       public void onComplete(@NonNull Task<GoogleSignInAccount> task) {
           if (task.isSuccessful()) {
              try {
                   GoogleSignInAccount signInAccount = task.getResult(ApiException.class);
              } catch (ApiException apiException) {
                   System.out.println("CATE_RESULT_CODE " + apiException.getLocalizedMessage()+" " +apiException.getStatusMessage()+ " " +apiException.getMessage()+ " "+apiException.getCause() );
              }
           } else {
                try {
